I believe I have found the problem. I don’t appear to have the mp3 codecs installed. Rhythmbox gives me the following error “The GStreamer plugins to decode “MP3″ files cannot be found.” I’ve started to look around in the package manager, but I’m not sure what I need to get in order to fix the problem.

Geez, I feel like such a n00b.

Nevermind. I found what I was looking for. in fact, I’m listening to music from my server in Rhythmbox right now. I still have one problem, though. The playlists I created in Firefly or in iTunes on my other machines aren’t showing up. All I see is the entire library. Any suggestions on how to correct this on either the server or client side?
